AI Article Synopsis
- A new optical platform achieves a record data rate of 1.92 Terabits per second using 40 wavelengths at 48 Gb/s each, without requiring high-speed components on the user side.
- The system successfully operates over a distance of 100 km with a passive split ratio of 1:64, showcasing efficient data distribution.
- This experimental setup demonstrates potential for delivering broadband speeds of 1 Gb/s to over 1000 users, indicating a significant advancement for future optical access and metro networks.
Article Abstract
Record 1.92-Tb/s (40λ × 48 Gb/s/λ) coherent DWDM-OFDMA-PON without high-speed ONU-side ADCs/DACs/DSP/RF clock sources is demonstrated over 100 km straight SSMF with a 1:64 passive split. Novel optical-domain OFDMA sub-band selection, coherent detection, and simple RF components are exploited. As the first experimental verification of a next-generation optical platform capable of delivering 1 Gb/s to 1000(+) users over 100 km, the new architecture is promising for future optical access/metro systems.
